The 10A8 PWM servo amplifiers are designed to drive brush type DC motors. The 10A8 model is fully protected against over-voltage, over-current, over-heating and short-circuits across motor, ground and power leads. This amplifier interfaces with digital controllers or can be used as a stand-alone drive. The model 10A8 requires only a single unregulated power supply. A potentiometer is located on the side for loop gain adjustment.
